A field experiment was performed to studying interaction effect of nitrogen levels and plant row spacing on yield and yield components of cotton vs. Golestan. After canola harvesting, treatments were arranged and planted by split plots in basic randomized complete blocks design with 4 replications. Plots were 4 nitrogen levels including 0, 50, 100 and 150 percent of recommended fertilizers amounts as main plots and 40, 60, 80 and 100 cm plant row spacing as sub plots. Before planting, fertilizer recommending was determined basis of soil testing in 0-30 cm depth. Results showed significantly increasing yield, plant height and vegetative and reproductive branch lengths. Decreasing plant row spacing decreased boll number per plant, plant height, vegetative and reproductive branch lengths and weed density per square meter so that the lowest boll number per plant, plant height, vegetative and reproductive branch lengths and weed density per square meter were obtained 40 cm plant row spacing. This treatment produced the highest total and first picking yield. On yield increasing, boll number per square meter had the more effect than boll number per plant because plant density increasing in area unit reduced boll number per plant, in contrast, plant density increasing in area unit increased boll number in area unit.
